Answer:

D. 70​

Step-by-step explanation:

If VX is the bisector of V, then UX=WX.

This implies that:

[tex]3z-4=z+6[/tex]

Group similar terms:

[tex]3z-z=4+6[/tex]

[tex]2z=10[/tex]

z=5

WU=2(z+6)

WU=2(5+6)

WU=2(11)=22 units

VW=VU=5z-1

Put z=5 to get;

VW=VU=5(5)-1

VW=VU=25-1

VW=VU=24

The perimeter of VWU=24+24+22=70 units

Answer:

Perimeter of triangle VUW = 70.

Step-by-step explanation:

Since VX is angle bisector and VX is perpendicular to UW then triangle UVX is congruent to triangle WVX using ASA property.

then UV=WV...(i) {corresponding sides of congruent triangle are equal.}

and UX=WX ...(ii)  {corresponding sides of congruent triangle are equal.}

then 3z-4=z+6

3z-z=6+4

2z=10

z=5

then UW=(3z-4)+(z+6)=3(5)-4+(5)+6=22

WV=5z-1=5(5)-1=24

UV=WV=24

Then perimeter of triangle VUW is

UV+WV+UW=24+24+22=70

Hence final answer is:

Perimeter of triangle VUW = 70.

Answer: THIRD OPTION

Step-by-step explanation:

We need to remember that a right angle is an angle that measures 90 degrees.

By definition, when two or more lines intersect (or cross one another ) at a 90-degree angle, then these lines are called "Perpendicular".

Therefore, in this case, we know that these two lines intersects at a right angle (angle of 90 degrees), then, we can conclude that these lines are Perpendicular.

This matches with the third option.

Answer:

Perpendicular lines

Step-by-step explanation:

Two or more lines are called intersecting lines.That point would be on each of these lines.

Answer:

f(6) = 2

Step-by-step explanation:

Since y is a function of x, that is y = f(x), f(6) implies that we shall be evaluating the value of y when the value of x is 6.

To do this we shall draw a vertical line, x = 6 and check where this line intersects with the graph of the function f(x)

The vertical line x = 6 intersects with the graph of the function f(x) on the horizontal line y = 2. The function f(x) assumes the value 2 for values of x between 4 and 8. Therefore,  f(6) = 2

Answer: Last option.

Step-by-step explanation:

We know that input values of a function are the values of the variable "x" and output values of a function are the values of the variable "y".

By definition, in functions each input value have one and only one output value.

Then, find [tex]f(6)[/tex] you can see that the input value is [tex]x=6[/tex] and you need to find the corresponding ouput value (or "y")

You can observe in the figure attached that the value of "y" for  [tex]x=6[/tex] is  [tex]y=w[/tex], obtaining the point (6,2)

Therefore:

[tex]f(6)=2[/tex]

This matches with the last option.

Answer:  Third option

[tex]y = |x + 1|[/tex]

Step-by-step explanation:

The main function

[tex]f (x) = | x |[/tex]

has its vertex in the point (0, 0)

The function shown in the graph has its vertex in the point (-1, 0)

The transformation made to f (x) that moves its vertex one unit to the left is:

[tex]y = f (x + 1)[/tex]

After this transformation the new function is:

[tex]f (x) = | x + 1 |[/tex]   Note that this function corresponds to the function plotted in the image.

Therefore the answer is the third option

Answer: x=10

Final answer:

The solution to the equation involves applying the quadratic formula to a rearranged version of the equation, solving for the value(s) of x. This can only be done accurately if the initial equation is correctly presented without typos.

Explanation:

The original equation presented by the student has a typo. However, using information provided, we can approach similar equations to demonstrate the solving process. For instance, the equation (2x)² = 4.0 (1 - x)² involves taking the square root of both sides to find the value of x. This involves rearranging and solving the quadratic equation that is created when you expand and combine like terms.

When solving a quadratic equation, such as ax² + bx + c = 0, we may use the quadratic formula: x = (-b ± √(b²-4ac)) / (2a), which will provide the two potential values of x. This process is crucial when the value of x is not a small enough percentage of a coefficient in the equation to use approximation methods.

If we were solving an equation like x² + 0.00088x - 0.000484 = 0, we would apply the quadratic formula to find the exact values of x.

Answer:

The probability is  0.0015

Step-by-step explanation:

We know that the average [tex]\mu[/tex] is:

[tex]\mu=500[/tex]

The standard deviation [tex]\sigma[/tex] is:

[tex]\sigma=100[/tex]

The Z-score is:

[tex]Z=\frac{x-\mu}{\sigma}[/tex]

We seek to find

[tex]P(x>800)[/tex]

The Z-score is:

[tex]Z=\frac{x-\mu}{\sigma}[/tex]

[tex]Z=\frac{800-500}{100}[/tex]

[tex]Z=3[/tex]

The score of Z = 3 means that 800 is 3 standard deviations from the mean. Then by the rule of the 8 parts of the normal curve, the area that satisfies the conficion of 3 deviations from the mean has percentage of 0.15%

So

[tex]P(x>800)=0.0015[/tex]

Answer:

26 units

Step-by-step explanation:

As the sales for the same month in past four years is given, they will be used to determine the sales for next month.

We have to find the average of previous 4 years' sale for the same month

So,

n = 4

The formula for average is:

[tex]Avg = \frac{Sum of values}{number of values}[/tex]

[tex]=\frac{ 24+30+23+27}{4}[/tex]

[tex]= \frac{104}{4}[/tex]

[tex]= 26[/tex]

26 is the average number of units that can be expected to be sold the next month ..

based on the previous average sales, one can expect to sell an average of 26 units next month.

To calculate the average number of units one can expect to sell next month based on past sales, we need to find the mean of the provided sales data. The actual sales data for the last four years are 24 units, 30 units, 23 units, and 27 units. To find the average (mean), we add up these amounts and then divide by the number of data points.

The sum of the units sold is 24 + 30 + 23 + 27 = 104 units. Since there are four years of data, we divide 104 units by 4 to get the average.

Average units sold = 104 units / 4 = 26 units.

Therefore, based on the previous average sales, one can expect to sell an average of 26 units next month.

Answer:

[tex]P=338\ in[/tex]

Step-by-step explanation:

we know that

The perimeter of the red figure is equal to

[tex]P=2[22+27+22+98][/tex] ----> because the sides of the figure are tangent to the circle

[tex]P=2[169][/tex]

[tex]P=338\ in[/tex]

Answer:

Step-by-step explanation

Perimeter is sum of the measurement of all sides of a polygon . The polygon we have in this question is formed by using the tangents from a given circle .

The concept we are going to use here is that if we draw two tangents from the same point outside on a given circle, the length of both tangents are always equal .

There are 8 sides of this polygon , That means there are four pairs because length of them are equal .

So perimeter is equal to two times the sum of four sides given to us .

Perimeter = 2( 22+27+22+98)

Perimeter = 2(169)

Perimeter = 338 in

Answer:

Option A.

Step-by-step explanation:

The given expression is

[tex]-25[/tex]

According to the reflexive property of equality, all values are equal to itself.

a = a

where, a be any real number.

Using the reflexive property we can say that

[tex]-25=-25[/tex]

It means -25 is equal or equivalent to -25.

Therefore, the correct option is A.

Note: If the given expression is [tex]\sqrt{-25}[/tex], then

[tex]\sqrt{-25}=\sqrt{25}\sqrt{-1}[/tex]        [tex][\because \sqrt{ab}=\sqrt{a}\sqrt {b}][/tex]

[tex]\sqrt{-25}=5i[/tex]             [tex][\because \sqrt{-1}=i][/tex]

Then the correct option is B.

Answer:

(1,9),(3,7),(5,5) (7,2)

Answer with explanation:

The sum of two distinct variables is 10.

  x + y=10

It is linear equation in two variables.

To plot this graph in two dimensional plane find two distinct points satisfying the equation.

x=0, gives , y=10 or , y=0 gives , x=10.

x=1, gives ,y=10 -1,→y=9

So,two ordered pairs lying in the coordinate system are , (0, 10) and (1, 9) or (10,0) and (1,9), you will get the equation of line.

Otherwise , you can Draw the graph of this function by writing the equation in Slope Intercept form which is as:

  [tex]\frac{x}{10}+\frac{y}{10}=1[/tex]

By writing the slope intercept form of line shows that , the line passes through , (10,0) and (0,10) means cutting x axis and y axis at these two points.

which rounds to 329 ← 3 significant figures

0.0032876 ≈ 0.00329

Answer:

y = 4x - 6.

Step-by-step explanation:

Slope-intercept form is y = mx + c where m = the slope and c = the y-intercept.

4x = y +6

Subtract 6  from both sides:

4x - 6 = y

we would write it as y = 4x - 6.

Answer:

Slope intercept form

y = 4x - 6

Step-by-step explanation:

Slope intercept form y = mx + b

In this case 4x = y +6

Re-write

y + 6 = 4x

Subtract 6 from both sides

y = 4x - 6  <-------Slope intercept form

The tan of angle C in triangle XYZ is 0.8.

To find the tan of angle C, we first need to determine the values of angle C, side XC, and side ZC. In triangle XYZ, angle Y is a right angle, so angle C must be angle Z. Since side YZ is opposite angle X, side YZ is equal to side XC.

Using the Pythagorean theorem, we can find side XC:

XC = sqrt(XY^2 + YZ^2)

= sqrt(3^2 + 4^2)

= sqrt(9 + 16) = sqrt(25) = 5.

Now, we can calculate the tan of angle C using the formula tan(C) = opposite side (YZ) / adjacent side (XC).

Therefore, tan(C) = 4 / 5 = 0.8.

Answer:

Step-by-step explanation:

Say that your equation is 2x+4=8, x=2

you would plug in the 2 where your x is so, 2(2) +4=8

then you'd solve regularly.

Step-by-step explanation: multiply the population by 0.02, round it to the nearest whole number, and then multiply that number by 3 and add it onto 53,768

The population of Oak Forest in three years will be approximately 57,091.

To find the population of Oak Forest in three years, we can use the formula for exponential growth. The formula is: P = P0 * (1 + r)t, where P is the final population, P0 is the initial population, r is the growth rate, and t is the number of years. In this case, P0 is 53,768, r is 0.02 (2% as a decimal), and t is 3. Plugging these values into the formula, we get:

P = 53,768 * (1 + 0.02)3

Simplifying the expression inside the parentheses:

P = 53,768 * (1.02)3

Calculating (1.02)3:

P = 53,768 * 1.0604

Calculating the final population:

P ≈ 57,091

Therefore, the population of Oak Forest in three years will be approximately 57,091.

Answer:

(2, 3)

Step-by-step explanation:

There is an easy way to solve this.

Set it up like this, where one end point is on top of the midpoint.

To get from 6 to 4, you subtract 2. So subtract 2 from 4 (that's where the x coordinate comes from). To get from 1 to 2, you add 1. So add 1 to 2 (that's where the y coordinate comes from)
